VALVE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Original application led January 17, 1913,`Seria1 No. 742,720. Dividedand this application-filed May 27,

1915. Seria1`No. 30,852.

To all whom it may concern.'

Be it known that FRANCIS M. Rrrns, de?

ceased, late a citizen of the United States, residing at Ithaca andSlaterville Springs, New York, in the county of Tompkins and State ofNew York, did invent certain new and useful Improvements in Valves forInternal-Combustion Engines, (described in his previous application,Serial No. 742,720, filed January 17., 1913, of which this is adivision,) of which the following is a specification.

Tle object of this invention is to produce a simplified form of valvemechanism for an internal combustion engine.

Another object of the invention is to provide an improved device bywhichthe combustion in an internal combustion engine is secured.

These and other objects of the invention will be fully illustrated inthe drawings, described in the specification and pointed out in theclaims at the end thereof.

This application is a division of prior vapplication No. 742,720, onwhich Patent 1,178,181 was issued April 4, 1916,.to which reference ismade for a more complete disclosure.

In the accompanying drawings, Figure 1 shows a vertical section throughthe valve mechanism, the section being taken on the line 1"-1x of Fig.2. Fig. 2 is' a verticalr section through .the valve mechanism, the`section being taken on the line 2"-2 of Fig. 1. Fig. 3 is a verticalsection takenl through the baffle plate and cylinder head, the sectionbeing taken on the line 3L-3" of Fig. 2. Fig. 4 is a. horizontal sectionthrough the valve chamber, the section being taken on the line 4* X ofFig. 2.

In the accompanying drawings like reference numerals indicate likeparts. y

In the drawings reference numeral 1 indicates a cylinder f an engine onwhich is fastened acylinder head 2. In this cylinder head is a. valvechamber at the bottom of which is located 'a baiile plate 3 having anopening 4 extending therethrough. A nozzle 5 is placed at one end ofthis opening having an air supply tube 6 and an oil supply tube 7communicating therewith. The air supply tube 6 connects with the tube 8through .which air under pressure is: frnished to the valve chamber foruse inthe engine. Through the nozzle 5 a mixture of 55 oil and air isblown through the tube 4 and is burned therein for the purpose of heats,ing the baffle plate through which the opening goes. The opening 4 isenlarged .at 20 `for the purpose of increasing the combustion space andto reduce the thickness of into the outer air. Centrally on this baffleplate is formed a valve seat 9. Concentric with the seat 9 a flange 10is formed in the valve-chamber and on this flange is formedJO a valveseat 11, the seat 11 being concentric with the seat 9. The seats 9 and11 may be referred to as two concentric ta ering sury faces of a singlevalve seat. (l)

which has a central opening 13 therein with which opening communicatesthe oil supply tube 14, the valve being formed with an up- `wardlyextending tube 15 which surrounds the stationary tube 14 and makes a.tight 80 sliding connection therewith. The tube 14 is stationary andvthe valve 12 is free -to rise and fall so as to control the feed of oilfrom the tube 14 to the baffle 3.

For the purpose'of lifting the valve a 85 rocker arm 16 is provided,pivoted at 17 and operated by a link 18, which link is driven from'arock shaft of the engine in the usual manner.

As the valve 12 rises it lifts from both the 90 seat 9 and the seat 11.Oil is admitted past the seat 9 and compressed air is admitted past theseat 11. The air and oil come' into contact with each other and intocontact with the baffle plate 3 which is maintained 95 at an ignitingtemperature, first by the torch or nozzle 5 and afterward as a result ofthe combustion. This causes the oil to burn with the air which burningis continued through a' definite interval of time 100 rather than duringmerely an instant which would characterize an explosion as ordinarilyoccurs in a -combustion engine which the charge is mixed and compressedPatented Feb. 6, 1917.

operating with the valve seats 9 and ll'is a valve 12 75 before ii isignited. while iii this engine,

with which this valve mechanism will beused, the combustion will beginas soon as the valve lifts to admit the air and oil to the baffle plateand will continue until the valve closes again. The valve will not lift`until the forward stroke of the piston is labout to. begin and thevalve will remain open for a considerable fraction of the piston stroke.That is, through one sixth or a l third or even one half or more of the180 iinto the engine cylinder,

pif further combustion. the piston of the engine is pressed down and ofthe piston stroke.

To lsecure theadmission of oil past the valve seat 9 the `oil in thetube 14 is kept under suiiicient pressure to cause the oil to feedagainst the resistance of the compressed air which is fed past the valveseat 11. As the compressed air and oil burn the volume of it increases.does not increase. If it did the air would ybe pushed back through thetube 8, cutting Instead, however,

the products of combustion advance from the baffle through the openings21 and as they advance from the baffle they expand causing the engine togenerate power. As they advance they make room for the air and oil thatpasses the valve 12 to support the combustion -which continues as longas the valve remains open. To insure 'proper feed the parts will beproportioned so that the pressure in the enginev cylinder is slightlyless than the pressure'in the air pipe 8;.
